LOCK.

Specification of Letters Patent.

Patented Oct. 9, 1906.

Application filed March 3,1906. Serial No. 304,026.

sash-locks, one object of the invention being to provide a simple-and inexpensive con struction of lock which may be readily adjusted to lock both sashes in closed position against movement, to permit but a limited opening movement of the sashes, or to release the sashes to allow them to be moved to a fully-opened position.

Afurther object is to provide a construction whereby the meeting-rails of the sashes will be drawn closely together when said sashes are fully closed.

In the accompanying drawings, Figure 1 is an inner elevational view of a window frame and sashes, showing the application of the lock thereto, the lock being arranged in the position it occupies to permit a limited opening movement of the sashes, the range of movement of one of the sashes being indicated in dotted lines. Fig. 2 is a detail view illustrating the position to which the lock is adjusted to disconnect the members thereof -to allow the sashes to be fully opened. Fig.

3 is a full-line longitudinal section through the lock arranged in the position shown in full lines in Fig. 1 and also shows in dotted 5 lines the reversed position of the lock to fasten the sashes against movement. Fig. 4 is Fig. 5 is an elevation looking toward the pivotal ends of the lock members. Fig. 6 is a cross-section through the brackets and pivoted ends of the lock members. Figs. 7 and 8 are detail perspective views of the pivotally connected interlocking ends of the sash members.

Fig. 9 is a fragmentary plan view, partly in section, showing one of the links and its brackets and illustrating a modification in the -means for drawing the rails of the sashes together when the lock members are in locking position.

Referring to the drawings, 1 and 2, respectively, represent the meeting-rails of the upper and lower window-sashes, to which are fastened bearing-brackets 3 and 4, respectively, each provided with an internallythreaded socket 5, receiving threaded pivot lugs or bosses 6 and 7, respectively, formed upon the adjacent ends of the members 8 and 9 of the sash-lock. The said members 8 and 9 comprise bars or links arranged in parallel relation and pivotally and adjustably connected by the bosses 6 and 7 to the bearingbrackets, so as to permit them to beswung to a horizontal position on either side of the central line of the brackets or through a re,-

dius of one hundred and eighty degrees. The threads of the bosses are so arranged as to draw upon the brackets when the members of the lock lie in a horizontal position to bring the rails 1 and 2 close together, and to spread said rails apart when the lock is swung to a position in order to allow the sashes to have free movement. a g

The link or block member 8, which is pivotally mounted upon the rail 1 of the upper sash, is provided at its outer or free end with a pair of spaced ears 10, perforated to receive a transverse coupling-pin 11, extending across the space between said cars, which space communicates with an inwardly beveled or inclined recess 12. The free end of the link member 9, which is pivotally connected with the meeting-rail of the lower sash, is provided with a hook 13 to pivotally engage the pin 11 and normally couple the two members or links for simultaneous move ment, while permitting of their free disconnection when said links are moved to a determined position. The face of the member 9, which engages the face of the member 8, is cut away adjacent to the hook 13 to form a central rib or enlargement 14. and opposite beveled faces or recesses 15 to respectively close the groove 12 and receive the projecting portions of the ears 10 of the member 8, thus permitting the connected ends of the links to have free pivotal movement. A dowel-pin or projection 16 projects from the link 8 to engage a seat or recess 17, formed in the link 9 to connect and hold the two links from lateral movement when in parallel relation and prevent them from spreading. An inclined or beveled groove 18 leads rearwardly from said seat or toward the pivoted end of the A member 9 to allow the-dowel 16 to ride readily out ofsaid recess when the link is disconnected by an endwise sliding movement of one upon the other, as hereinafter described.

Fig. 1 shows in full lines the arrangement'of the lock for comiecting the sashes in such manner as to permit them to have a limited opening movement, from which it will be seen that the links are horizontally arranged at the right of the central line of the bearing-brackets, with the link 8 disposed above the cooperating link 9. Hence it will be understood that the lower sash may be raised or opened to an extent equivalent to the combined lengths of the links when folded out in longitudinal alinement, as indi cated in dotted lines in Fig. 1, and that the upper sash is permitted to have a correspond ing opening movement, the links swin unison from a horizontal to a vertical position in the opening and closing movements of the sashes. Further movement of either sash beyond the limited extent named will, however, be effectually prevented as the links remain in connection with each other, and thus couple the sashes, so that one sash will resist opening movement of the latter beyond the distance allowed by the coupled links. In order to lock the sashes wholly against movement and in fully-closed position, the lock device is swung on its pivotal connection to a horizontal position, the reverse of that shown in Figs. 1 and 3, or to the left of the center line of their supportingbrackets. This adjustment reverses the position of the links 8 and 9, so that the link member 8 will lie under the link member 9. Such arrangement will therefore prevent an opening movement of either sash, as the link 8 cannot swing, owing to the fact that such movement is prevented by the link 9, while the latter is prevented from having upward swinging movement by the former. Hence, as it is necessary that the links attached to the respective-sashes swing in the directions of opening movement of said sashes to permit the sashes to be opened, it will be readily understood that the sashes will be locked in closed position. In this position the meetingrails 1 and 2 are also drawn closely together by the action of the threaded or beveled connections between the links and their bearingbrackets. When it is desired to permit the sashes to be freely opened and closed to their fullest extent, the links are swung from the position shown in Fig. 1 or that shown in dotted lines in Fig. 3 to a vertical position and the lower sash elevated, whereby upward sliding motion of the link 9. on the link 8 will be effected, thereby moving the hook 13 out of engagement with the pin 11 and disconnecting the links. The links may then be swung backward out of connection on the respective rails of the sashes, and the latter will be free to be adjusted in the usual man ner. It will be understood that the inclination of the groove 18 permits the seat portion 17 of the link 9 to move out of engagement with the dowel 16 when the link 9 is slid upward in the manner described and that the inclined portions 15 of the member 9 act in such adjustment as cam members riding on the projecting portions of the ears 10 to swing the link 9 away from the link 8 in such ing in opening movement to effect a free release of the coupling arts.

In Fig. 9 Thave shown a modified construction of means for drawing the rails of the sashes together when the locking-links are adjusted to lock the sashes in fully-closed position. The bracket 3 is here shown provided with a bearing-flange 5, havin a bearing-opening 5 and an outer bevele or inclined face 5, while the link 8 is provided with a bearing-boss 6, j ournaled in said bearing-opening and carrying a lug 6 The beveled surface 5 is so arranged that when the link is swung to the left to hold the sash fully closed the lug will engage the beveled surface and draw the rail 1 inward, while when the link is swung to a vertical position, or to the left, the lug will be out of contact with the beveled surface and permit the rail to move out to its usual position. It will be understood, of course, that the mountings of both links will be constructed in this fashion, so that when the links are swung to a fulllocking position the rails will be drawn together, while when the links are swung to release position or to a position to allow the sashes to have a limited opening movement the rails will be allowed to spread to permit free movement of the sashes.

I do not, of course, limit the invention to the particular form of detachable pivotal connection between the outer ends thereof herein shown, as any means for this purpose falling within the purview of the appended claims may be employed.

Having thus described the invention, what is claimed as new is 1. A sash comprising bearing-brackets adapted to be fixed to the meeting-rails of the sashes, and links having pivot members engaging said brackets, the pivot members and brackets having a threaded connection where.

by the meeting-rails will be drawn together and spread apart in the closing and opening movements of the sashes.

2. A sash -fastener comprising a pair of bearing-brackets adapted for respective connection with the meeting-rails of the sashes, and links pivotally connected at one end with said brackets and provided, respectively, at their opposite ends with interconnecting members adapted to be released by a sliding movement of one link upon theother.

3. A sash lock comprising a pair of supporting-brackets adapted for respective connection with the meeting-rails of the upper and lower sashes, and links pivotally connected at one end with said bearing-bracket, one of said links being provided at its outer end with a pin and the other with a hook to engage said pin, the links having coacting means to throw the hook out of engagement with the pin when the hook-carrying link is longitudinally moved upon the other link, substantially as described.

ITO

4. A sash-lock comprising supportingbrackets adapted for respective connection with the meeting-rails of the sashes, links pivotally connected at one end with said bearing-brackets, one of said links being provided the other.

5. A sash lock comprising supportingbrackets adapted to be fixed to the meetingrails of the upper and lower sashes, links pivotally connected at one end to said brackets, one of said links being provided at its free end with a pair of spaced ears and a pin connecting the same and the other link at its free end with a hook to engage said pin, and cam-surfaces on opposite sides of said hook to engage the ears and move the hook out of engagement with the pin when one of the links is adj usted longitudinally in one direction with respect to the other, one of said members being further provided with a dowel-pin and the other with a dowel seat and an inclined groove leading thereto.

6. A sash-lock comprising a pair of supporting-brackets having threaded sockets, and links provided at one end with threaded pintles engaging said sockets, said links having a pivotal connection at their outer ends, said pivotal connection comprising members adapted tobe connected and disconnected by a sliding movement of one of the links upon the other.

7. A sash-fastener comprising a pair of links, means for pivotally connecting the links at one end with the meeting-rails of sashes, and a pivotal connection between the other ends of the links adapted to permit disconnection of the links upon the adjustment of the latter to a determined position.

In testimony whereof I affix my signature in presence of two witnesses.
